Mechanical properties of unidirectional aligned bagasse fibers/vinyl ester composite

Abstract

<jats:title>Abstract</jats:title> <jats:p>The present study describes the preparation of aligned unidirectional bagasse fiber-reinforced vinyl ester (BFRVE) composites and their mechanical properties such as tensile, flexural, shear and impact strength. Composites were prepared by a hand lay-up technique developed in our laboratory with the help of a hot press. Mechanical properties were obtained for different fiber contents by varying the number of layers. The obtained tensile property values were compared with the theoretical results. The results show that the tensile strength increased linearly up to 44 wt% and then dropped. However, the tensile modulus increased linearly from 17 wt% to 60 wt%. In the case of flexural properties, the flexural strength increased up to 53 wt% and started to decrease. However, the flexural modulus also increased linearly up to 60 wt%. The impact strength values were higher than the matrix materials for all the specimens. The short beam shear strength values were also increased up to 53 wt% and then dropped. The modified Bowyer and Bader (MBB) model followed by the Hirsch model shows a very good agreement with experimental results in both tensile strength and modulus.</jats:p>

Evaluation of mechanical and thermal properties of tamarind seed filler reinforced vinyl ester composites

“…The tensile, flexural, impact, and shear properties are evaluated, and the orientation of the fiber is also compared. Tensile and flexural strengths reach their maximum at 44 and 53 wt%, respectively, whereas 17 wt% of composites gives better result in all mechanical properties than pure resin .…”

“…The agro bio‐waste fillers play the crucial and vital role in environmental constraints with an excellent potential alternative for synthetic fiber polymer products, due to the plenty of availability and economical processing. The introduction of new natural fillers in a polymer matrix can provide significant advantages compared to the traditional fillers used in composites and they also increases worldwide, due to the impact of low cost, low density, renewable, biodegradable, desired properties, and environmental friendliness material . Tamarind ( Tamarindus indica L.) is a member of the dicotyledonous family Fabaceae (Leguminosae), and it grows in more than 50 countries of the world such as India, Bangladesh, Sri Lanka, Thailand, and Indonesia, and in the African countries.…”

Effects of Chemical Modification on the Mechanical Properties of Calotropis Gigantea Fiber-reinforced Phenol Formaldehyde Biocomposites

“…Composite plates were prepared using hand lay-up technique by a mould with the size of 150 × 150 × 3 mm [18]. First, poly vinyl alcohol as a releasing agent was applied on the inner side of the mould to ensure easy removal of cured composite plates.…”

“…This approach has been used extensively in solving several optimization problems such as minimization of drilling induced damages in composites [12][13][14][15], significance of parameters in the stage and satellite separation processes [16,17], and on the performance of heat exchangers [18] and other manufacturing problems [19][20][21][22][23][24][25]. Design and manufacturing group of authors contributed a lot relevant to the development of materials [26][27][28][29][30][31][32][33], fabrication aspects [34][35][36], and industrial/engineering optimization problems [37][38][39][40][41][42][43][44] for the benefit of the readers of the journal.…”
